CULTIVATO R.

SPECIFICATION forming part of Letters Patent No. 233,379, dated October 19, 1880. Application filed December 4, 1879.

To all whom it may concern Be it known that I, SPENCER R. STANTON, of Oxford, in the county of Oakland and State of Michigan, have invented certain new and useful Improvements in Cultivators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, refer- IO ence being bad to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

The nature of my invention consists in the construction and arrangement of a'cultivator,

as will be hereinafter more fully set forth.

In the annexed drawings, which fully illustrate my invention, Figure l is a perspective view of my cultivator. Figs. 2, 3, and 4 are detailed views of parts thereof.

The frame of my cultivator is made entirely of gas-pipe, which may be filled with wood, as shown, if desired.

A is the main part of the frame, and forms the front and sides thereof, all in one piece. The sides are connected together by means of cross-pieces B G and T-couplings l) D, made expressly for this purpose. The T-couplings D D have holes large enough for the frame A to pass through, and are then fastened by keys on the underside and the cross-piece B screwed into the sides of said couplings. The couplings D D are made exactly the same, and the cross-piece 0 passed through them and the sides of the frame screwed into them.

F is the axle, passing through boxes attached to the sides of the frame, and formed with a crank at each end, on which the driving-wheels E are placed. The axle F is provided with an arm, G, connected by a rod, a, 0 with a lever, H, which is pivoted to a rack, I, attached to one of the sides of the frame. By these means the cultivator-frame maybe raised and lowered as desired, and held by a pawl on the lever H taking into the rack I.

J is the tongue, securely fastened and braced to the frame. To this tongue is fastened the center front standard, L. To the cross-bar B are secured two standards, L L, and to the cross-bar 0 are fastened four standards, L 50 Each of the six standards is, by a rod, b, connected with a clip, (1, on the front part of the frame. Each of these clips has two or more holes through them, as shown in Fig. 3, so as to adjust the connecting-rod and give more or less pitch to the standard. The standards are also braced sidewise by means of braces f, fastened by clips 0 to the cross-bars of the frame, so that they can be moved to allow the standards to be adjusted sidewise.

The various standards are provided with shovels K, as shown. The shovels on the standards L are formed with mold-boards K, to turn a furrow or dirt upside down, instead of shoving it, as others do.

M M are shields attached to beams N N, which are hinged at their front ends and connected bya bent cross-bar, O, to let good sized corn pass through, said cross-bar being connected by a cord, h, with the rear cross-bar, O.

P P represent the handles, fastened to the rear side standards, L by means of flanged castings R. Thehandle is placed between the flanges of the casting and fastened by a pin or bolt after being raised or lowered to suit the operator. The casting R is pivoted to the back of the standard, and has its lower end slotted laterally, as shown at r, and a bolt, i, passing through said slot. By this means the handle can also be adjusted sidewise as required.

In connection with the cultivator, I also use a drag, S, having a rod, m, at each end, so arranged as to fit in the ends of the rear crossbar, 0, and make a hinge for the drag, so as to level the ground for the drill.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with the front framebar, A, and the standards of a cultivator, of the brace-rods 0, clips d, having two or more holes for adjusting said rods, the side braces, f, and movable clips 6, substantially as and for the purposes herein set forth.

2. The flanged casting 1t, having slot 4", laterally adjustable, as described, in combination with the vertically-adjustable handle P, as and for the purposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand and seal this 26th day of November, 1879.

SPENCER R. STANTON. [L. s.]
